当Facebook用户发布照片或状态更新时，数据似乎会飘进“云端”，这并不是一个虚幻的地方，而是一个复杂的数据中心，用的能量和小镇一样多。在俄勒冈州中部的脸书普莱尼维尔数据中心不顾这种耗能的类型，通过先进的技术，包括创新的机械设备顶楼和蒸发冷却系统，已经取得了LEED黄金的地位，所有这些都保持了数据的流动，并提供了舒适的工作空间。

Facebook Prineville Project Synopsis When Facebook users post photos or status updates, data seemingly drifts into the “cloud,” which is not exactly an ethereal place, but rather a complex data center housing racks of servers using as much energy as a small town. Defying this energy-draining typology, the Facebook Prineville Data Center in central Oregon has achieved LEED Gold status through advanced technologies, including an innovative mechanical equipment penthouse and evaporative cooling system, all while keeping data flowing and providing pleasant workspaces.

由于安全性要求，数据中心通常是类似堡垒的。Facebook是一家以开放为荣的公司，对它来说，建筑师们创造了一座与其高沙漠景观相协调的显赫建筑。可渗透的，但安全的周界是覆盖在温热色调预制混凝土面板，波纹钢和分层玻璃。“人的空间”，包括会议室和工作空间，开放到室内庭院。事实上，每个员工都喜欢至少两个方向的视野和自然光线。

Due to security requirements, data centers are typically fortress-like. For Facebook, a company that prides itself on openness, the architects created a prominent building that harmonizes with its high desert landscape. The permeable yet secure perimeter is clad in warm-toned precast concrete panels, corrugated steel and layered glazing. “People spaces,” including conference rooms and workspaces, open onto an interior courtyard. In fact, every employee enjoys views and natural light from at least two directions.

该设施用于机械冷却的能量为零。电脑设备室和机械阁楼一起作为一个被占用的空气处理程序。风扇墙从外面吸入干燥的沙漠空气，然后喷雾注入水分并降低温度几度，以保持服务器正常运行。毕竟，facebook普雷尼维尔数据中心有点像云。

The facility expends zero energy towards mechanical cooling. Computer equipment rooms and the mechanical penthouse together function as an occupied air handler. Fan walls pull in dry desert air from outside, and then misters inject moisture and drop the temperature several degrees to keep servers functioning properly. The Facebook Prineville Data Center is a little cloud-like, after all.

为了达到世界上最节能的数据中心之一的地位，更不用说严格的LEED Gold要求，Facebook Prenniille数据中心的设计者必须重新考虑数据中心建筑、机械、电气和计算系统的每一个部分，并删除所有没有直接提高效率的东西。剩下的系统元件必须协调运行，从处理器到风扇墙，再到蒸发器，再到减震器控制装置。

Sustainablity To reach the status as one of the world’s most energy efficient data centers, not to mention rigorous LEED Gold requirements, the designers of the Facebook Prineville Data Center had to rethink every part of a data center’s building, mechanical, electrical, and computing systems and remove everything that didn’t directly benefit efficiency. The remaining system elements had to operate in concert, from processors to fan walls to evaporative misters to damper controls.

一有机会，电力使用量就被削减，这使得一座比其他最先进的数据中心运行效率高38%的建筑成本降低了24%。数据中心的效率取决于其功率利用率(PUE)，它衡量的是计算机设备的总能耗除以能耗。理想比率为1.0，环境保护局定义的行业最先进的评级为1.5.根据初步测试的结果，普雷尼维尔设施获得了接近完美的1.07PUE分数。

Power usage was cut at every opportunity, resulting in a building that runs 38% more efficiently than other state-of-the-art data centers yet cost 24% less to construct. A data center’s efficiency is determined by its power usage effectiveness ratio (PUE), which measures the total energy consumption divided by the consumption for the computer equipment. An ideal ratio is 1.0, and the EPA-defined industry state-of-the-art rating is 1.5. Based on the results of preliminary tests, the Prineville facility has achieved a near-perfect score of 1.07 PUE.

除了令人印象深刻的数据记录了facebook普雷尼维尔数据中心的能源效率，其他可持续的功能还包括采用低VOC材料、太阳能电池板阵列，以及在室内庭院内安装一个雨水储水罐，以满足灌溉需要并为厕所供水。

In addition to the impressive statistics documenting the energy efficiency of the Facebook Prineville Data Center, other sustainable features include the incorporation of low-VOC materials, solar panel arrays, and a rainwater storage tank within the interior courtyard that satisfies irrigation needs and supplies water for toilets.
